Dot product of matrix, MATLAB in Engineering

Assignment Help:

Dot Product:

The dot or inner product of two vectors a and b is written as a • b and is defined as

In another words, this is like matrix multiplication when multiplying a row vector a by a column vector b; and the result is a scalar. This can be accomplished by using the * operator and transposing the second vector, or by using the dot function in a MATLAB:

>> vec1 = [4 2 5 1];

>> vec2 = [3 6 1 2];

>> vec1*vec2'

ans =

        31

>> dot(vec1,vec2)

ans =

        31
